A basic diafine q.

[haempe]

How many rolls can I run through a quart of diafine without replenishing? Found no note about that on the package... read this somewhere but can't found it again...
TIA

Keep going until there is no longer enough Diafine to fill your tank. You will loose some off 'A' every time you use it as it is absorbed by the film.

It does not need replenishing.

I agree with the above.
I've been using my latest batch for three years and about 150 films.
When I do replenish, it will be to get more volume in solution "A". I'm down to having only enough to cover one 35mm film in a small tank.

Lancaster, when you do mix up a fresh batch dump the excess off 'B' so that you have the same volume off 'A' and 'B' before adding it to the new batch.

I've done just under 90 roll's off film from a two litre bottle, I have about half left in bottle 'A' but bottle 'B' often exceed's the two litres that I started with so the excess goes down the drain.

Almost time to mix up another batch.

Thanks, Robert and Mike.
That reassures me.
